In the early 1990s American Laser Games released several of their arcade shooting game titles on IBM-PC CD-ROM. The games feature hundreds of full motion video scenes, where each scene accounts for different actions taken by the player, namely when you shoot the bad guy and he falls dead, or when the bad guy shoots you.

The games were intended for 286/386 hardware. Video sequences were presented at 10 fps, using VGA (~320x200x256) resolutions and accompanied by 8-bit mono sound. The README files accompanying some games suggest the video compression algorithm is called "IBM PhotoMotion", however this has not been verified.

Trivia: The original game relied upon the intra/inter pixel refresh to clear away bullet hole marks drawn directly on the output buffer.

The game was developed to run smoothly on a single-speed CD-Drives. Thus, assuming 10 fps playback rate, each frame size may not exceed 15kb (not including it's sound portion), while full VGA screen takes 320*200 = 64k of data. Due to this speed limits, video becomes very lossy/blocky in the fast-changing scenes. Authors even included separate video files for double-speed CD-ROMs with a bit improved picture quality.

MM Chunk Type 0x000d ("Inter Half-Horiz Video")

MM Chunk Type 0x000f ("Inter Half-Horiz Half-Vertical Video")

Identical to type 0x0005, except each compressed sample refers to two horizontal (across) and two vertical (down) pixels.

MM Chunk Type 0x0002 ("Raw Video")

The raw video chunk is not used by the games evaluated, but was found to be a a working feature of the game engine (decoder). It was stumbled across when testing how the game engine handled unsupported chunk types.
